Abstract

The utility model provides a high-efficiency energy-saving jet engine. The utility model is characterized in that a combustion chamber and turbines which are connected in series in multiple stages are arranged in a heat insulating water tank; a nozzle pipe of the turbine of each stage is provided with a steam inlet pipe. Heat radiation of the steam inlet pipes can be fully used and is ejected to the turbines to work, and the exhaust emission temperature can be cooled down to be lowest finally; the heat efficiency is improved, and the energy is saved.

Description

Energy-efficient air breathing engine

The utility model relates to air breathing engine.

The human reciprocal feed pump of just having invented from 1782 plays extremely important impetus to industrial expansion at that time.The mankind had invented petrol engine again in 1876, invented diesel engine in 1892.People by the Steam Engine Age of heaviness, invent the New Times of wideling popularize internal-combustion engine by unremitting effort in these 200 years.Internal-combustion engine comes compared with steamer, and not only light and handy, efficient has also improved a lot, and the 8%-15% by steamer has brought up to 30%-40%.The mankind have invented the steam-injector type aircraft again since the forties, and this just makes production high speed large aircraft become possibility.People have made the rocket jet motor from carrying fuel and oxygenant in recent decades, and this has just promoted modern high-tech field---the development of aerospace industry.Up to the present, internal-combustion engine is done the suitable heat of useful work, and with the exothermic ratio of fuel perfect combustion, the peak efficiency of instant heating machine also has only about 40%.Wherein also have the heat of suitable most not to be used for doing useful work.First: cylinder interior stroke of piston is shorter, and fuel breaks out back piston and is pushed when doing work the arrival maximal end point, and the waste gas that the temperature of cylinder interior and pressure are also quite high just is discharged from, and these waste gas have been taken away considerable heat in vain.Second: the entire cylinder body all is immersed in the water tank heat radiation system.The heat that cylinder block and piston absorb is all passed to the water in the water tank, has taken away considerable heat during water boiling vaporization.Next is a part of energy consumption in the overcome friction acting, as the friction between piston and the cylinder wall, and the friction of each parts joint.

The purpose of this utility model provides a kind of energy-efficient air breathing engine.

Its technological scheme is as follows: it by heat-insulation and heat-preservation water tank, water tank be filled with water, be placed in the water tank the firing chamber and successively the series connection the multi-stage impeller unit form.Have high-pressure oil pipe and high-pressure air tube to introduce from the outside and communicate with the firing chamber, the sparger that spark plug is housed in addition communicates with the firing chamber.The exhaust steam pipe of first order turbine communicates with the nozzle pipe of second level turbine, promptly serves as nozzle pipe, and same, partial exhaust steam pipe is the nozzle pipe of the third level.The rest may be inferred, and the afterbody exhaust steam pipe leads to outside drain.On nozzle pipe at different levels, be provided with steam inlet duct.

Water tank can be made into single-bin or multi-chamber, and valve, water pump control break-make are arranged between two storehouses.

In the above-mentioned structure, its essential characteristics is the heat radiation of firing chamber and turbines at different levels can be absorbed heat by the water in the water tank, after waiting to seethe with excitement; Its water vapor from steam inlet duct that nozzle pipes at different levels communicate enter, spray to acting in the turbine again, like this, can not waste heat energy, efficient improves greatly, and is energy-conservation.The utility model simple structure, ingenious adopts the multistage turbine combination, and it is extremely low that final toxic emission temperature is reduced to; Fully energy-conservation, and do not need special starting device (as motor), but the just proper functioning of need only lighting a fire is easy to use.

Be illustrated below in conjunction with drawings and Examples:

Fig. 1 is a structural representation of the present utility model.

As shown in Figure 1, the utility model by the heat-insulation and heat-preservation water tank that is filled with water (comprising main water box 1, secondary water tank 2), be positioned at the firing chamber 3 of main water box, introduce high-pressure oil pipe 4, the high-pressure air tube 5 communicate with the firing chamber and the sparger 6 that spark plug is housed from the outside, second level turbine 7, draw third level turbine 8, fourth stage turbine 9 compositions in secondary water tank.

On the nozzle pipe 10,11,12 of the second level, the third level, fourth stage turbine, be respectively equipped with steam inlet duct 13,14 and 15, be provided with valve 16 control break-makes in the major-minor water tank, the water that also is provided with between the water pump 17 control major-minor water tanks flows to keep major-minor water tank water temperature to tend to balance.Also be provided with filler pipe 18 on the water tank, the exhaust steam pipe of afterbody turbine leads to the outside.Also have, be provided at an outer portion with high-pressure air pump and high pressure oil pump (figure part omitted), for the firing chamber provides high-pressure air and high pressure oil.Its working principle is that one-level promotes the one-level acting, and is simple and clear, need not state more.

Claims

1, a kind of energy-efficient air breathing engine, it is characterized in that: it is by the heat-insulation and heat-preservation water tank, water tank is filled with water, the multi-stage impeller unit that is placed in the firing chamber in the water tank and connects is successively formed, having high-pressure oil pipe and high-pressure air tube to introduce from the outside communicates with the firing chamber, the sparger that spark plug is housed in addition communicates with the firing chamber, the exhaust steam pipe of first order turbine communicates with the nozzle pipe of second level turbine, promptly serve as nozzle pipe, equally, partial exhaust steam pipe is the nozzle pipe of the third level, the rest may be inferred, the afterbody exhaust steam pipe leads to outside drain, is provided with steam inlet duct on nozzle pipe at different levels.
